Hi, for the past 4 semesters (Fall 2018, Spring 2019, Fall 2019, and Spring 2020) it was roughly $4700 each semester ($18,800 total). The required international experience is anywhere from $2000-3000 depending on the class you take and the country you go to (this doesn't include flight, transportation, food and drink, staying longer in the country or around there since you get the whole summer off!). Also, the "required international experience" isn't required, but if you forgo it you have to do 40 hours of community service and take an extra 1 unit mindfulness class. Some say that takes up more time than is worth the money you save plus having a reason to visit a new country is always super fun!. FWII will be 6 units which I think it part time and there are two FWII. I don't know the price but I don't think it's the same as $4700 (but someone correct me if I'm wrong). So, if I had to guess, the entire academic portion if under $25,000.
I didn't have to take out loans myself but I believe you can get unsubsidized loans no matter what as long as you applied for FAFSA on time. I think those are the ones that accrue interest right away instead of being deferred until after graduation because we're grad students. There are scholarships out there within the department and within SJSU that you could always apply to as well. I've seen them range from $500-2000. A lot of the students also get part-time jobs on campus or off if you have a special skill.
I don't believe you can pay tuition monthly, but I could be wrong on that as well! If you get unsubsidized loans, I think you are required to pay it before the semester starts.
Hope that helps.
